Technology stocks were also big gainers, with Apple(AAPL) jumping more than 7%.

The day's gains were the biggest since early September for the Dow and S&P 500. The Nasdaq had its best day since July.

The broad rally started last Friday, after President Obama and congressional leaders wrapped up their first fiscal cliff meeting since the election. Investors were encouraged after both Democrats and Republicans emerged from the meeting with a confident tone and suggested that agreement could be reached before Jan. 1, when federal spending cuts and tax increases are scheduled to take effect.

"The question of whether or not the fiscal cliff will be avoided is impossible to answer with any degree of certainty, but the political reality does indicate that some sort of compromise may be possible," said Bob Doll, senior advisor at BlackRock. "The two sides still appear to be quite far apart on some important issues, particularly regarding a potential tax increase for higher-income Americans. But the parties are at least attempting to avoid brinksmanship."

While the rhetoric out of Washington is slightly more positive, experts think stocks will remain under pressure and trading will likely be choppy until an actual deal is finalized, which is still likely weeks away.

Even factoring the day's gains, the three major indexes are well off their multi-year highs reached earlier this fall. The Dow and S&P 500 are down about 6% from those levels, while the Nasdaq is down more than 8%. Last week, the tech-heavy index had briefly entered correction territory when its slide has extended to 11%.

Meanwhile, two better-than-expected reports on the housing market also gave markets a lift Monday.

And the National Association of Home Builders' sentiment index rose for a seventh straight month to 46, its highest level since May 2006. Analysts were expecting a reading of 42.
